HELP I DON'T KNOW THIS !!
I will give brainliest to the CORRECT ANSWER :(

260 in²

Step-by-step explanation:

1) Find the total area of the triangular sides

Plug in 10 in as the base and 8 in as the height

Multiply the area by 4 (for the 4 triangular surfaces)

Therefore the total area of the triangular sides is 160 in².

2) Find the area of the square base

Plug in 10 as the length

Therefore, the area of the square base is 100 in².

3) Add the areas together

100 in² + 160 in²

= 260 in²

Therefore, the surface area of the solid is 260 in².

I hope this helps!

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6
